NASHVILLE, Tenn. -- A man charged in aexpressed suicidal thoughts in June and had a volatile relationship with a woman which twice led to law enforcement intervention this year, according to police records.
Emanuel Kidega Samson, 25, is charged with the fatal shooting of one woman and is expected to face several more charges following the rampage that left six others wounded on Sunday.
According to an affidavit filed with the court, Samson told Nashville police following his arrest that he arrived at the church armed and fired upon the building. Court documents do not indicate whether Samson has an attorney in advance of his first court hearing Wednesday.
Police records in Murfreesboro, about 20 miles southeast of the church, show that Samson's father reported that his son had texted him on June 27 to say "Your phone is off, I have a gun to my head, have a nice f------ life."
He was then reported missing by family members who said he was threatening suicide, and police were notified, according to CBS affiliate WTVF.
Officers in January responded to two domestic disturbances between Emanuel Samson and a woman who accused him of cheating on her. Samson cut his hand when he punched a small TV on her desk, according to statements to police.
Samson also allegedly took the woman's phone, at which point she went to a neighbor's home to call police, according to the incident report obtained by the station.
In March, police were dispatched to Samson's home. Samson told police the woman was trying to enter his house despite his attempts to break off contact. He told officers he was afraid of her because she had struck him in the past.
No charges were filed in either incident.
WTVF reports Samson was enrolled in an unarmed security course two days before the shooting. Buford Tune, owner of the private security instruction company Academy of Personal Protection and Security, told the station he made the realization Monday, after checking over class paperwork from the previous week.
Tune said the six-eight hour class covers various laws surrounding security guards in Tennessee. Tune said Samson was referred to his class by Samson's employer — a security guard agency he declined to identify — and Samson had worked Saturday night as a guard for that company, just hours before allegedly opening fire at the church.
State records show Samson previously held an unarmed security license in Tennessee beginning in January 2014, but the license expired two years later without being renewed, reports WTVF.
Authorities said the ordeal began just before 11:15 Sunday morning as services at Burnette Chapel Church of Christ were being let out, CBS News correspondent Errol Barnett reports.
Member Minerva Rosa said members were talking about the success of their yard sale the previous day when they heard gunshots outside the building. The church pastor, David Spann, 60, then shouted for everyone to run, according to a witness.
The gunman entered the church from the back after fatally shooting a woman outside, police said. He then walked through the church silently, firing "indiscriminately," shooting six more people before an usher subdued him, police said. Police later recovered another pistol and a shotgun from the suspect's vehicle.
Rosa said the reading that day had been from Luke, Chapter 8, and she recalled the part about a woman who touched Jesus and was cured of bleeding.
By the end of the shooting, she was on her knees, her dress stained with blood, putting pressure on the gunshot wound in Pastor Spann's chest. She and others got on their phones to call 911.
The 22-year-old usher, Robert Engle, tackled the gunman and suffered injuries when he was pistol whipped. In the struggle, the shooter shot himself, although it wasn't clear if it was on purpose or an accident. Engle retrieved his own gun from his car and held the man until police arrived, police said.
"He's amazing," Rosa told reporters about Engle. "Without him I think it could be worse. He was the hero today."
There were about 42 people inside the church, including a class of Sunday school children, WTVF. 10-year-old Jeremiah Reese told the station he helped his teacher barricade the classroom until police arrived.
The boy told the station he started crying when he realized his family hadn't been injured.
"When I realized they were alive, I just started pouring out crying," Reese said. "I realize I'm 10 and I'm supposed to be tough, but I just couldn't hold it in though, I just couldn't hold it in."
Authorities said Samson came to the United States from Sudan as a child in 1996 and is a legal U.S. resident.
No motive has been immediately determined. Church members told investigators that Samson had attended services a year or two ago, said Don Aaron, a spokesman for the Metro Nashville Police Department.
Nashville police did not immediately comment on several bizarre posts on the suspect's Facebook page in the hours before the shooting.
One post read, "Everything you've ever doubted or made to be believe as false, is real. & vice versa, B."
Another post read, "Become the creator instead of what's created. Whatever you say, goes."
And a third post read, "You are more than what they told us."
Melanie Smith, 39, of Smyrna, Tennessee, was killed when the shooter opened fire in the parking lot. Spann's wife, Peggy, 65, was also shot as well as William and Marlene Jenkins, 83 and 84 respectively, Linda Bush, 68, and Katherine Dickerson, 64. Police said none of the surviving victims suffered life-threatening injuries.
Smith's children Breanna Smith, 19, and RJ Smith, 12, remembered their mother as caring, witty and intelligent.
"There's no understanding why he did it. Everybody is looking for why, why, why," Breanna Smith told WTVF. "There's no understanding evil, there's no understanding hate."
